Urban Scanner project

Research Objectives

Urban Scanner is an integrated platform that provides high-resolution spatiotemporal air quality information within urban environments. It collects and combines a variety of information such as air pollution concentration, a 3D map of the city, traffic conditions, micro-weather patterns, etc.

Partnerships

Project partners: Scentroid Inc.

Funding Sources

Natural Sciences and Research Council of Canada (NSERC) Engage Grant, Health Effects Institute (HEI) grant

Trainees

Traffic, air quality, and environmental justice

Research Objectives

Disparities in exposure to traffic-related air pollution have been widely reported, while little work has been done to simultaneously assess the impact of vehicle types on populations of different socioeconomic/ethnic backgrounds. In this study, we employed a machine learning approach to spatially distribute light-duty vehicle and heavy-duty truck emissions across the city of Toronto from 2006 to 2020. We examined associations between these emissions and different marginalization indices across this time span.
